Manage jobs added

i recently used this to turn off my wifi at a set time

@echo off
at 18:00 netsh interface set interface "Wireless Network Connection" DISABLED
pause

 

but then now, every 18:00, it would close down the wifi, but i only wants once, and if needed here's what it says when i run the batch file:

added new job with job ID = 13

and the job id just keeps piling up, how can i get rid of all the jobs?
